Сylindrical charged bunches dynamics in the longitudinally inhomogeneous plasma
Results of analytic study and computer simulation of the cylindrical charged bunches' dynamic are presented. Analytic solution was obtained for cold plasma in the given current approximation. Results of the computer simulation of the ion bunch are in a good agreement with theoretical estimation...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Results of analytic study and computer simulation of the cylindrical charged bunches' dynamic are presented. Analytic solution was obtained for cold plasma in the given current approximation. Results of the computer simulation of the ion bunch are in a good agreement with theoretical estimations. The wake field has a behavior of the spatial beating because the phase difference between the waves excited by forefront and rearfront varies along the bunch trajectory. Dynamics of the electron bunch differs strongly due to the formation of the microbunches' with complex dynamics. The wake field magnitude increases substantially due to the microbunches' focusing. The first microbunch is better focused longitudinally and defocused in the radial direction in comparison with the next microbunches. It results to different spatial structure of the wake field at the axis and at the periphery of the system. |
